Ink jet recording method for recording pattern layer and white overlaying layer on longitudinal sheet
The present invention relates to an ink jet recording method for recording a white overlaying layer and a non-white pattern layer to a recording medium, printed matters obtained by the recording method, and systems for realizing the recording method thereof.
1. A recording method in which a printing image including a white ink layer and a non-white ink layer is recorded to an opaque recording medium, the method comprising:
providing the white ink layer to the recording medium, and providing the non-white ink layer to the white ink layer,
wherein a white ink composition for the white ink layer contains hollow polymer fine particles or a porous inorganic pigment as a colorant,
wherein the ink discharge amount per unit area of the white ink layer is larger than the ink discharge amount per unit area of non-white ink layer, and
wherein the resolution of the non-white ink layer is lower than the resolution of the white ink layer.
2. The method according to claim 1 , wherein a size of an ink droplet discharged for recording the white ink layer is either larger or smaller than that of an ink droplet discharged for recording the non-white ink layer.
3. The method according to claim 1 , further comprising drying the white ink layer, the non-white ink layer being provided after the drying.
4. The method according to claim 1 , the recording medium having an ink reception layer being used.
